My hon. Friend makes an important point, and he will be pleased to learn that the Government are more than doubling the amount of money that we put into dementia research. We need to catalyse the private sector companies because although they know that the size of their potential market of people with dementia is huge, they have been frustrated in their attempts to find the breakthrough medicine that we urgently need. We need to use the research to excite their interest and keep them focused on this truly tragic disease.
